The political wheel turns quickly.
No sooner than it had been confirmed that Minister for Finance Paschal Donohoe was leaving Cabinet, the rumours of who might replace him began to swirl around Leinster House.
This is a Fine Gael position, and so it's up to Tánaiste Simon Harris to take the decision.
Don't expect him to dwell too long on it.
The Finance portfolio is too important to leave in abeyance.
The likelihood is that it will be someone inside Cabinet, as they would need to have that experience under the belt.
Of course, Mr Harris could decide that he is the best person for the job.
That's the big rumour.
Speculation says he will be replaced as Minister for Foreign Affairs, Trade and Defence by Helen McEntee, who is currently Minister for Education and Youth.
If accurate, she would be immediately plunged into planning for Ireland holding the six-month Presidency of the European Council next year.
Yet rumours can turn out to be inaccurate.
A strong contender for the finance brief would be Peter Burke, the current Minister for Enterprise, Tourism and Employment.
He's a chartered accountant, already in an economic brief, and viewed as a steady pair of hands.
In the past, he was Minister of State for European Affairs which would help his pitch.
Minister for Health Jennifer Carroll MacNeill is often touted as a possible future leader of Fine Gael and securing the finance portfolio would be a significant boon.
However, she's just finding her feet in her current department, and the inclination might be to let her continue in what's a challenging brief - especially given it's her first time at the Cabinet table.
As new arrivals into Cabinet, it also seems an unlikely pole-vault for Patrick O'Donovan, the Minister for Culture, Communications and Sport, or Martin Heydon, the Minister for Agriculture, Food and the Marine.
Fianna Fáil has made it clear that their ministers will not be re-shuffled because of Mr Donohoe's departure.
Fine Gael is expected to announce a decision on who will take over in the Department of Finance by late afternoon.
Then expect the next round of rumours about which Fine Gael Minister of State is likely to make the big jump to a senior ministry.
The focus of speculation so far is on Hildegarde Naughton, who is a "super junior minister" and therefore is already sitting at Cabinet.
If Ms McEntee moved to Foreign Affairs, she could slot into the vacant brief of Education and Youth.
Then, Fine Gael would feel the need to bolster its position in Dublin, with Mr Donohoe's departure.
He may be in Brazil at COP30, but Minister of State Neale Richmond must be hoping he gets a position as a "super junior", and a seat at the Cabinet table, on his return from the Amazon.
